For the first time ever, the 3 Hemingray made AM.TEL.& TEL.CO. Marked insulators are together for a photo :) First it the One of a kind CD 106, CD 121 with SDP (a bit more scarce then the SB ones) and the 190/191.

Interesting observations on the CD 106. The mold lines and embossing are very crisp. Clearly made in a new mold. You can see the turning lines on the mold.

Perhaps AM Tel chose to go with the 121 over the 106 and this 106 was a sample? Not sure. It was found in the early 1970s at an Omaha flea market. The AM Tel 106 has been one of my top Hemingray wants for years. Very happy to be the new owner of it.
